I-5G, idatha enkulu, ubuhlakani bokwenziwa nobunye ubuchwepheshe bunezidingo eziphakeme zokucubungula idatha kanye nomkhawulokudonsa wenethiwekhi.Izikhungo zedatha zidinga ukuqhubeka zithuthukisa umkhawulokudonsa wenethiwekhi ukuze zihlangabezane.Ngakho-ke, kunesidingo esiphuthumayo sokuthuthukisa umkhawulokudonsa wenethiwekhi ezikhungweni zedatha kulezi zinsuku, ikakhulukazi Izikhungo zedatha ye-inthanethi.Indlela eqondile kakhulu yokwandisa umkhawulokudonsa wenethiwekhi ukwandisa umkhawulokudonsa wenethiwekhi yechweba elilodwa ukusuka ku-40G kuya ku-100G, kusukela ku-100G kuya ku-200G, noma ngisho nangaphezulu, ngaleyo ndlela ukwandisa umkhawulokudonsa wesikhungo sonke sedatha.Ochwepheshe babikezele ukuthi iningi le-400GbE ukuthunyelwa kuzoqala ngo-2019. 400GbEamaswishiizosetshenziswa njengomgogodla noma umnyomboamaswishiezikhungweni zedatha ezinkulu kakhulu, kanye nomgogodla noma umgogodlaamaswishiezikhungweni zedatha yamafu ezizimele nezomphakathi, ukwazi ukuthi i-100G nayo iyathandwa. Eminyakeni emithathu edlule, manje sekudingekile ukushintshela ku-400G, futhi umkhawulokudonsa wenethiwekhi ukhula ngokushesha futhi ngokushesha.
Ngakolunye uhlangothi, kunesidingo esinamandla samamojula wesivinini esikhulu esikhungweni sedatha, futhi ngakolunye uhlangothi, izinga lokuhluleka kwemojula liphezulu.Uma kuqhathaniswa ne-1G, 10G, 40G, 100G noma ngisho ne-200G, izinga lokuhluleka elinembile iphakeme kakhulu.Yebo, inkimbinkimbi yenqubo yalawa mamojula anesivinini esiphezulu kakhulu kunaleyo yamamojula anesivinini esiphansi. Isibonelo, imojula ye-40G ebonakalayo iboshwe iziteshi ezine ze-10G. Ngesikhathi esifanayo, ilingana nama-10G amane asebenzayo, inqobo nje uma kunenkinga. I-40G yonke ngeke isakwazi ukusetshenziswa, futhi izinga lokuhluleka liphakeme kune-10G, futhi imodyuli ye-optical idinga ukuxhumanisa umsebenzi wezindlela ezine ze-optical, futhi amathuba ephutha aphakeme ngokwemvelo.I-100G ingaphezulu nakakhulu, ezinye ziboshwe iziteshi ze-10 10G, kanti ezinye zisebenzisa ubuchwepheshe obusha be-optical, obuzokwandisa amathuba okuba nephutha.I-100G ingaphezu kwalokho, ezinye ziboshwe iziteshi ze-10 10G, kanti ezinye zisebenzisa ubuchwepheshe obusha be-optical, obuzokwandisa amathuba okuba nokwenzeka. Iphutha.Ingasaphathwa isivinini esiphezulu, ukuvuthwa kobuchwepheshe akuphakeme, njenge-400G kusewubuchwepheshe endaweni yokucwaninga, izokwethulwa emakethe ngo-2019, kuzoba nomvuthwandaba omncane wezinga lokuhluleka, kodwa inani alikho ekuqaleni. Kuyoba khona okuningi, futhi njengoba ubuchwepheshe buqhubeka buthuthuka, ngikholelwa ukuthi buzozinza njengemodule ye-vulgar.Cabanga ukuthola i-module ye-1G optical ye-GBIC eminyakeni engu-20 edlule. Kuyafana nomuzwa wokusebenzisa i-200G manje. Kuyinto engenakugwenywa ukuthi umkhiqizo omusha uzokhuphuka izinga lokuhluleka esikhathini esifushane.
Ngenhlanhla, iphutha lemojula ye-optical linomthelela omncane kusevisi. Izixhumanisi kusikhungo sedatha zenzelwe ikhophi yasenqolobaneni kakhulu. Uma imojuli ye-optical yesixhumanisi esisodwa inenkinga, isevisi ingathatha ezinye izixhumanisi. Uma kuyiphakethe lephutha le-CRC, lingaphinda lidlule ekuphathweni kwenethiwekhi. Ngokushesha kwatholakala ukuthi inqubo yokumiselela yenziwa ngaphambi kwesikhathi, ngakho-ke ukwehluleka kwemojula yokubona akuvamile ukuba nomthelela omkhulu ebhizinisini. Ezimweni ezingavamile, imojuli ye-optical ingase ibangele ukwehluleka kwembobo yedivayisi, okungabangela yonke idivayisi ukuba ilenge. Lesi simo ngokuvamile sibangelwa ukusetshenziswa kwedivayisi okungenangqondo, futhi akuvamile ukwenzeka. Phakathi kwamamojula amaningi abonakalayo namadivayisi kuhlanganiswe Ngokukhululekile, nakuba kuxhunywe ndawonye, akunabudlelwane bokuhlanganisa. Ngakho-ke, nakuba ukusetshenziswa kwamamojula we-high-speed optical kubi nakakhulu, umthelela ebhizinisini awumkhulu kangako. Ngokuvamile, ngeke kudonse ukunaka kwabantu. Kutholakala ukuthi iphutha lishintshwa ngokuqondile, futhi isikhathi sokugcinwa kwe-high-speed optical module futhi side. Iphutha ngokuyisisekelo likhululekile. Ukushintshwa, ukulahlekelwa akukukhulu.
Amaphutha emojula yokubona abangelwa kakhulu ukwehluleka kwembobo ukuphakama, imojuli yokubona ukuze ingabonakali, kanye nephutha lembobo ye-CRC. Lawa maphutha ahlobene nohlangothi lwedivayisi, imojula yokubona ngokwayo, kanye nekhwalithi yesixhumanisi, ikakhulukazi ukusho okungalungile nokwehluleka UKWENZA. Nquma indawo yephutha kusukela kubuchwepheshe besofthiwe. Ezinye ziseyinkinga yekilasi lokuzijwayeza. Ayikho inkinga phakathi kwezinhlangothi zombili, kodwa akukho ukulungisa iphutha nokuvumelana phakathi kwazo, okwenza kube nzima ukusebenzisana. Lesi simo sisesiningi, ngakho-ke amadivaysi amaningi enethiwekhi azonikeza ukujwayela. Uhlu lwemojula ye-optical ludinga amakhasimende ukuthi asebenzise amamojula awo aguquliwe ukuze aqinisekise ukutholakala okuzinzile.Uma kunephutha, indlela engcono kakhulu isewukuhlolwa kokuzungezisayo, shintsha isixhumanisi se-fiber optical, shintsha imojula, shintsha imbobo, ngokusebenzisa lolu chungechunge lokuhlola ukuze kuqinisekiswe. kungakhathaliseki ukuthi inkinga yemojula yokubona, noma inkinga yesixhumanisi noma yembobo yemishini, ngenhlanhla, ngokuvamile lolu hlobo lwephutha luqinisekile ngokuqhathaniswa, kunzima ukubhekana nalolo hlobo lwephutha alilungisiwe.Isibonelo, uma kune-CRC iphakethe elingalungile ethekwini, imojuli ye-optical izokhishwa ngokuqondile futhi kufakwe entsha. I-fault phenomenon izonyamalala, bese i-module ye-optical yasekuqaleni izoshintshwa futhi iphutha ngeke liphindwe, okwenza kube nzima ukwahlulela ukuthi kuyinkinga ye-optical module noma cha. Lesi simo ngokuvamile sibhekana nokusetshenziswa okungokoqobo, okwenza kube nzima ukwahlulela.
Indlela yokunciphisa izinga lokuhluleka kwamamojula okukhanya? Okokuqala, inaka ngokukhethekile umthombo, umkhawulokudonsa ophakeme wemojula yokukhanya ungagxumi emakethe, ukuze ugcwalise ukuhlolwa, futhi imojula idinga imishini efanele, qaphela ukuthi lawa masu nawo adinga ukuphelela ukuze avuthwe, imojula entsha. ukungena kahle emakethe, hhayi nje ukuphishekela isivinini esikhulu, imishini yenethiwekhi manje isekela amachweba amaningi, hhayi ama-400 g, ahlanganiswe nama-100 g amane nawo angahlangabezana nezidingo.Okwesibili, kufanele sinake ukwethulwa kwe-high-speed optical amamojula. Abahlinzeki bemishini yenethiwekhi kanye namakhasimende esikhungo sedatha kufanele baqaphele lapho kwethulwa amamojula okukhanya anesivinini esiphezulu, bakhulise ukuhlolwa okuqinile kwamamojula we-high-speed optical, futhi bahlunge ngokuqinile imikhiqizo enesici ngekhwalithi.Namuhla, umncintiswano wemakethe wamamojula we-optical wesivinini esiphezulu. unolaka.Bonke banethemba lokusebenzisa amathuba kumamojula amasha anesivinini esikhulu, kodwa ikhwalithi nentengo akulingani. Lokhu kudinga abathengisi bemishini yenethiwekhi namakhasimende esikhungo sedatha ukuthi bakhulise imizamo yabo yokuhlola. Uma izinga lemojuli liphezulu, kuba nzima nakakhulu ukuqinisekiswa.Okwesithathu, imojula yokubona iyidivayisi enezinga eliphezulu kakhulu lokuhlanganisa. Ishaneli yefayibha eveziwe kanye nezingxenye zangaphakathi zintekenteke uma kuqhathaniswa. Uma uyisebenzisa, kufanele iphathwe ngobumnene, ngamagilavu ahlanzekile ukuze ugweme ukuwela othulini, okuzophinde kunciphise Sebenzisa izinga lokuhluleka, imodyuli ye-optical engasetshenziswanga kufanele ifakwe i-fiber cap futhi ifakwe esikhwameni.Okwesine, isimo somkhawulo engaphansi ngangokunokwenzeka, njenge-100 g yemojuli yokukhanya esetshenziswa esimweni esiseduze nomkhawulo wejubane futhi isikhathi eside, imojuli yokukhanya yebanga lamamitha angama-200, futhi kufanele isetshenziswe ebangeni lamamitha angama-200, lawa manani omkhawulo. Ukusebenzisa i-wastage ye-optical module kukhulu, kufana nabantu, abantu basebenza ekamelweni lokupholisa umoya lika-24 ~ 26 degrees, ukusebenza kahle kuphezulu, ekushiseni okuphezulu kwama-degrees angu-35 ngaphandle kwemvelo, ukunaka akukwazi ukugxila isikhathi eside. isikhathi, ukusebenza kahle komsebenzi kuphansi kakhulu, ngama-degree angaphezu kuka-40, abantu beza ekushiseni futhi ukuthi basebenza kanjani. Ukunikeza indawo enethezekile yemojula ye-optical kungandisa ngempumelelo impilo yesevisi yemojula ye-optical.
Ngokukhula kwedatha enkulu, isidingo somkhawulokudonsa wezikhungo zedatha siya ngokuya sikhuphuka, futhi ukwethulwa kwamamojula we-high-speed optical kube ukuphela kwendlela yokulawula ikhwalithi.Uma amamojula amasha anesivinini esiphezulu eshaya udonga njalo emakethe, zizoqedwa. Yiqiniso, noma ibuphi ubuchwepheshe obusha bunenqubo evuthiwe, imojula ye-optical enesivinini esiphezulu ayifani, kudingeka ukuqhubeka nokuqamba izinto ezintsha kwezobuchwepheshe, ukuxazulula izinkinga ezihlukahlukene, ukuthuthukisa ikhwalithi yemojula, ukunciphisa amathuba okuhluleka. Imojuli yokukhanya enesivinini esiphezulu iyinjini yenzuzo yabakhiqizi bamamojula, futhi iyindawo eyinhloko yabakhiqizi bamamojula ezikhathini zasendulo ezidlule.
